any you see in a store these days are most likely some of the new style stryofoam okies. These have been made for some time now and the molds for making these are what broke recently.

The old style plastic ones are what people get "panty puddin" over, and more specifically the nail polish pink color that one legendary steelheader calls his alltime favorite. You can tell the difference pretty easy, just push your fingernail into it, it if makes a dent you don't have plastic.
